GET
Invoice change history

Overview

Returns the ordered firm_history events recorded against a fiscal invoice — create, update, storno, send, void, SPV submission, payment, etc. Each entry identifies the acting user.

Actor attribution

When the request is made with a mobile JWT, the acting user is the JWT subject. When made with an API key, the attributed user is the key’s owner (the user_id stamped on the api_key row). Entries prior to 2026-04-13 may report a system user_id of 0 — those predate the history attribution fix and cannot be retroactively repaired.
